On an electronics assembly line, one wrong part or one missing label can hold up a whole order. A large electronics manufacturer in India was handling kitting, defects, labels, stock transfers and scrap with too many manual steps. MXTechies built three connected Mendix apps for its FATP (final assembly, test and pack) operations, covering kitting, defect handling and storage, all linked to the plant’s existing MES, SAP and printing systems.
Electronics manufacturing traceability software tracks every part, board and label as it moves through production. In this project, the solution digitises FATP shop-floor processes in three Mendix apps: Kitting, Defect and Storage. Workers scan parts and boards instead of writing them down, labels print in bulk on Zebra printers, defective boards and scrap are tracked end to end, and data flows to and from MES, SAP and shop-floor systems through available APIs. The result is better traceability and fewer inventory mismatches.

The challenge
Many FATP activities depended on manual work:
- Master data set up by hand, leading to inconsistencies.
- Key parts and semi-finished goods tracked manually, leaving traceability gaps.
- Labels printed one by one, causing printing delays.
- Board stock transfers and part replacements done manually, risking inventory mismatches and wrong replacements.
- Defect cards, scrap movements and defective-board cartons handled on paper or email.
- System-to-system updates and order extensions handled by people, making monitoring and reporting hard.
The solution
MXTechies developed a centralised set of Mendix apps for FATP. They share one master data layer, send automated email notifications and connect to the plant’s existing MES, SAP, shop-floor and Zebra printing systems where APIs allow.
Scanning replaces typing, so every part, board and carton is tracked as it moves. Built-in validation checks part numbers automatically, and every scrap movement gets its own unique number.
Key features
01Master data management
- On the line
- Parts and settings are configured once, centrally.
02Scan-based tracking
- On the line
- Key parts and semi-finished goods are tracked by scanning.
03Order-wise serial retrieval
- On the line
- Serial numbers are pulled for each manufacturing order.
04Bulk label printing and reprinting
- On the line
- Labels print in batches on Zebra printers.
05Automated part-number validation
- On the line
- Wrong part numbers are caught before they cause errors.
06Defective-to-good board swapping
- On the line
- Faulty main boards are replaced and tracked properly.
07Red card generation
- On the line
- Defect cards are created and downloadable as reports.
08Scrap inward and outward tracking
- On the line
- Every scrap movement is recorded with a unique scrap number.
09Carton ID labels
- On the line
- Cartons of defective boards are labelled and tracked.
10Excel import and export
- On the line
- Bulk data moves in and out easily.
How it works
- Set upMaster data for parts and processes is configured in the app.
- KitOperators scan parts into kits for each manufacturing order.
- LabelSerial numbers are retrieved and labels print in bulk.
- Handle defectsDefective boards get a red card, are swapped for good boards and are tracked.
- Store and scrapStock transfers, defective-board cartons and scrap movements are recorded.
- Sync and reportData flows to MES, SAP and shop-floor systems, and reports are downloadable.

Outcomes
- More automation: fewer manual steps across kitting, defects and storage.
- Better data accuracy: validation and scanning cut errors.
- End-to-end traceability: parts, boards, labels and scrap are all tracked.
- Cleaner inventory: stock transfers and replacements are recorded correctly.
- Faster labelling: bulk printing replaces one-by-one printing.
Why build this on Mendix
- Shop-floor ready: Mendix supports scanning and fast screens for operators.
- Connects to plant systems: MES, SAP and Zebra printers integrate through available APIs.
- Three apps, one platform: kitting, defect and storage share master data.
Who this is for
Electronics manufacturing services (EMS) companies, smartphone and device assemblers, and any high-volume assembly plant that needs scan-based traceability, defect handling and label printing connected to MES and SAP.
Frequently asked questions
What does FATP mean?
Final assembly, test and pack: the last stage of electronics manufacturing before shipping.
Which systems does it connect to?
The plant’s MES, SAP, shop-floor information systems and Zebra label printers, through the APIs available.
Can it print labels in bulk?
Yes. Labels can be printed and reprinted in bulk, including carton ID labels.
How are defects handled?
Defective boards get a red card, are swapped for good boards with tracking, and are packed into labelled cartons.
How is scrap tracked?
Every scrap movement in and out is recorded with a unique scrap number.
